ACL Race rod bearings for Nissan SR20DET / SR20DE

ACL Race rod bearings are trimetal engine bearings designed for higher RPM conditions. Their combination of design, metallurgy and engineering is intended for demanding engine use.

The construction features a strengthened overlay plate and design solutions for improved bearing retention in the housing, heat transfer and hydrodynamic oil film formation.

• Trimetal construction with a high-strength overlay plate of reduced thickness for improved fatigue properties
• Hardened steel backs on all rod bearings to support the bearing lining and assist with bearing retention in the housing
• Increased crush for improved bearing retention
• No flash plating on the back to improve heat transfer and maximize grip between the bearing and its housing
• Increased eccentricity to compensate for bore distortion at high RPM and assist in hydrodynamic oil film formation

Suitable for: Nissan 100NX I (B13), Nissan 200SX I (S13).

Engines: SR20DET, SR20DE. Please check your vehicle’s engine code (registration document or VIN) before ordering; if in doubt, contact us and we will check for you.

Sizes

STD is the standard size for an unground crankshaft. Undersizes (−0.25 mm, −0.50 mm …) are for a reground crank, and “+0.025 mm clearance” (X) is for highly stressed engines. Your machine shop chooses the size after measuring.
